Hey Anton, do you maybe need to initialize it?

struct Book {
    let title: String
    let author: String
    let price: String?
    let pubDate: String?

    init(title: String, author: String, price: String, pubDate: String) {
        self.title = title
        self.author = author
        self.price = price
        self.pubDate = pubDate
    }

}

If yes, I am going to explain more :)

Yes, but it has to be failable initialisator which accepts dictionary values, and initializes stored properties Thanks
